Example of PSPP:GrandMaison

The two power stations at Grand'Maison have total

installed capacity of 1800 MW in turbine, 1275 MW in

pump operation.

The above ground powerhouse has four 5-jet Pelton units

with unit capacity 158.5 MW running under 922 m head

and with total discharge of 78 m3/s.

The underground power house measures 161 x 16 x 40 m

and has eight 4-stage pump-turbines, with unit capacity

152.5 MW (turbine) and 157 MW (pump), running under

955 m head and with total discharge of 144 m3/s (turbine)

and 138 m3/s (pump).

GRAND'MAISON Pumped Storage

Power Station includes:

The Grand'Maison dam (head work),

The Verney dam which is the lower reservoir,

Two power stations and the headrace works.

The evolving uses of PSP

Institutional evolutions : from a

regulated to a deregulated power market

Associated with large nuclear / thermal

capacity

Development of intermittent renewableenergy

17/21

Wind & Solar Issues

Intermittent Variable

Difficult to predict

Cannot meet fluctuating demand

No inertia

New and large electrical storage options are needed to compensate for

fluctuating generation.

Conclusion

Large development of renewable intermittent energy sources

Need for new balancing facility

Opportunity for PSP development

Chalenge for new PSP development is contractual arrangement &

financing
